I’ve been meaning to write up a longer post on this, but haven’t had time this week, so rather than let it slip by, I’ll just post the link and try to answer any questions that come up.

TU Delft has improved their protocols (== low-level physical procedures) for producing entanglement between two nitrogen vacancy centers in two diamonds held some distance apart.  And ETH Zurich has shown entanglement over 90cm of coax, between two superconducting qubits, which is a big deal since it can improve the scalability of superconducting systems, even if it’s not directly an approach for wide-area networking.

(I do think “on demand” is a bit of hyperbole, but the results are strong.)
